These parameters have not been addressed thoroughly in previous studies. Most investigators used only their own initial oil volume and equilibrium time during their experiments. The present study is focused on investigating the effects of these parameters under various initial oil volumes and equilibrium times according to the design of experiments. The optimum initial oil volume and equilibrium time to yield maximum swelling factor are determined. The initial oil volume and equilibrium time are found to contribute a positive impact to the swelling factor. Based on the results, the maximum initial oil volume is 3.4 cc or 85% of the total cell volume while the optimum equilibrium time is 101 min. The increment of the initial oil volume of.5 cc or 12.5% to 3.4 cc or 85% increases the swelling factor to 6.7% while the increment of the equilibrium time from 30 to 101 min increases the swelling factor to 4.9%. The study also found that the response surface method is appropriate to produce the optimum parameters in order to get maximum swelling factor.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Equilibrium time,initial oil volume,Optimum conditions,Swelling factor,Swelling test[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]equilibrium time,initial oil volume,optimum condition,Swelling factor,swelling test[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This work is a part of research supported by the Energy Resources R&D Program of the Korea Institute of Energy Technology Evaluation and Planning (KETEP) grant funded by the Korean Ministry of Trade, Industry & Energy.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1080/12269328.2018.1443402[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
